摘要
目的探讨上颌前牵配合快速扩弓在青少年骨性Ⅲ类错早期矫治中的应用,并评价其临床疗效。方法选取30例生长发育期骨性Ⅲ类错病例,随机分为两组,治疗组15例:上颌前牵配合快速扩弓;对照组15例:上颌前牵未配合快速扩弓。摄取X线头影定位侧位片,并测量分析,来评价治疗前后骨性和牙性变化。结果两种不同支抗设计的上颌前牵均可促进上颌骨发育,两组疗效差别无显著性。结论上颌前牵配合快速扩弓可用于青少年骨性III类错并横向发育不足的患者,更能有效地促进上颌的发育,下颌骨未见显著变化,患者牙颌面形态改善满意。
Objective To evaluate the effect of maxillary protraction and rapid palatal expansion on growing patients with skeletal class Ⅲ malocclusion.Methods 30 growing patients with skeletal class Ⅲ malocclusion were divided into 2 groups.15 patients were treated with maxillary protraction and rapid palatal expansion as treatment group.The others were treated with maxillary protraction without rapid palatal expansion as control group.Cephalometric analysis was compared using lateral cephalograms taken before and after treatment.there no significant different between maxillary protraction and rapid palatal expansion treatment group.Results Maxillary protraction and rapid palatal expansion effectly promote the development of maxilla,while was no significant effect on mandible.Conclusion Maxillary protraction and rapid palatal expansion on the treatment of growing patients with skeletal class Ⅲ malocclusion was improvement of the maxillary transverse deficiency.
